A vent flow apparatus and method for general application in venting and filling air pockets in conduit or duct type apparatuses designed for passage of material therethrough is provided including a hollow vent flow conduit preferably in the form of a tube having an entry opening and a downstream exit opening with both openings being in communication with a duct for flow of material therethrough. The entry opening is in communication with the duct at a first location of greater cross-sectional area of the duct than a second location of communication of the exit opening with the duct. The vent flow conduit has particular applicability for post-tensioning systems for concrete or other suitable structures, particularly post-tensioning systems which include body sections interconnected in series by an intermediate anchor head and which use a transfer means for routing grout between the body sections and around the intermediate anchor head.
